Not getting an error message; it just isn't connecting/finding any networks.

Could you please post a screenshot of the Wi-Fi page whenever you are at home and know that there is for sure a wireless network availalble?

What happened when the issue started ocuring? (Did you update the system, install a new app, jailbreak it, etc?)

Nothing. It just disconnected one night and never connected again.

Turn on airplane mode, and shut the phone down. Remove the SIM card as well, let it sit for about 5 minutes. After that, put the sim card back in, turn on the phone and then turn airplane mode off and see if you can see networks again.

If not, then I would suggest performing a factory reset on the phone.

Thank you.  Did all that and it still isn't working. My other apple devices and others' phones are able to connect to the various Wi-FI networks.

What happens if you choose 'Other' and type in the credentials for your router (i.e. both the SSID and the password)?

You did a full system restore? Meaning you have deleted everything and reinstalled iOS on it?
